The fluid mosaic model describes the plasma membrane as a flexible boundary of a cell. It protects the integrity of the cell along with supporting the cell and helping to maintain the cells shape. Vesicles may combine with plasma membrane to secrete contents Lysosomes Contain digestive enzymes Functions Aid in cell renewal Break down old cell parts Digests invaders Vacuoles Membrane bound storage sacs More common in plants than animals Contents Water Food wastes Mitochondria Break down fuel molecules cellular respiration Glucose Fatty acids Release energy ATP.
Made of 2 thin layers of lipid molecules. Protective barrier around cell. The folds of the inner membrane are called cristae.
